Housestaff Projects


After conducting research projects with their respective mentors, many residents choose to create posters and abstract presentations for local, regional, and national competition submission. The American College of Physicians offers an annual Colorado meeting and a local Denver meeting every year at which many residents present research abstracts. In addition, there is a Department of Medicine Research Day with excellent participation by and many award winners among the housestaff. Divisions within the Department of Medicine support residents to present at national subspecialty meetings. Each year, our residents receive recognition and awards at local, state and national meetings.
